(Population projection) The U.S. Census Bureau projects population based on the following assumptions: 1.One birth every 7 seconds 2.One death every 13 seconds 3.One new immigrant every 45 seconds Write a program that displays the population for each of the next five years. Assume the current population is 312,032,486 and one year has 365 days. Hint: In C++, if two integers perform division, the result is the quotient. The fractional part is truncated. #Beginner In gcc c++ compiler using namespace std; #include<iostream> using namespace std; int main() { long long int currentPopulation = 312032486; int perBirth = 7 ; //second ; int perDeath = 13 ; //second ; int perImmigrant = 45 ; //second ; cout<< "enter year to see population : " ; int year ; cin>>year; //get year long long int yearTosecond = yea...
(Find the number of years) Write a program that prompts the user to enter the min- utes (e.g., 1 billion), and displays the number of years and days for the minutes. For simplicity, assume a year has 365 days. #Beginner In gcc c++ compiler using namespace std; #include<iostream> using namespace std; int main() { int minutes; cout<< "enter the minutes : " ; cin>>minutes; const int year_per_minutes=365*24*60; const int day_per_minutes=24*60; int year=minutes/year_per_minutes; int day=(minutes%year_per_minutes)/(day_per_minutes); cout<< " " <<minutes<< " minutes is aproximately " <<year<< " years and " <<day<< " days" ; return 0; } copy Output enter the minutes : 1000000000 1000000000 minutes is aproximately 1902 years and 214 days [Program finished] Need of Programmer Need of Programmer ...
(Financial application: calculate tips) Write a program that reads the subtotal and the gratuity rate, then computes the gratuity and total. For example, if the user enters 10 for subtotal and 15% for gratuity rate, the program displays $1.5 as gratuity and $11.5 as total. #Beginner In gcc c++ compiler using namespace std; #include<iostream> using namespace std; int main() { float total , gratuity_rate ; cout<< " enter sub total and gratuity rate :" ; cin>>total>>gratuity_rate; float gratuity = total*gratuity_rate/100; float final_total = gratuity + total; cout<< "gratuity $" <<gratuity<< " final total is $" <<final_total; return 0; } Output enter sub total and gratuity rate :10 15 gratuity $1.5 final total is $11.5 [Program finished]
